Christians believe that all human life is sacred, unique and God-given. They also believe that all humans are made in the image of God.
Then God said, “Let us make mankind in our image, in our likeness, so that they may rule over the fish in the sea and the birds in the sky, over the livestock and all the wild animals, and over all the creatures that move along the ground.Genesis 1:26-27
Christians believe this to mean that many of the characteristics of God are reflected in humans. As a result, Christians believe that all human life should be treated with respect and dignity.
The belief that all humans are special can be seen in a document known as The Universal Declaration of Human Rights, which sets out all the different rights that every human should be entitled to.
